block/blk-map: Remove redundant assignment
Get rid of redundant assignment to a variable ret from function bio_map_user_iov as it is being assigned a value that is never read. It is being re-assigned in the first instruction after the while loop Reported by clang-tidy [deadcode.DeadStores] Signed-off-by: Michal Orzel <michalorzel.eng@gmail.com> Link: https://lore.kernel.org/r/20220423113811.13335-2-michalorzel.eng@gmail.com Signed-off-by: Jens Axboe <axboe@kernel.dk>
